COMBINED LETTER-SHEET AND ENVELOP.

T 0 all whom it may concern:

Be it known that I, LYMAN R. SWETT, a citizen of the United States, residing at Bos ton, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Combined Letter-Sheets and Envelops, of which the following is a specification.

My device consists in the combination of a return envelop and a writing sheet, formed integrally from a blank of original form, gummed and folded in a novel manner.

It also includes an apartment for the senders message.

The device is fully illustrated in the accompanying drawings, in which- Figure 1 is a plan of the blank from which the article is made. Fig. 2 is a plan of the same after one fold, and Fig. 3 is a similar view after the second fold, and ready for closing.

Numeral characters are employed to designate the various parts of the device, similar characters denoting corresponding parts in the several views.

The numeral 10 designates the body of the blank from which my invention is formed. This body is to be folded on the long line 25 and the perforated cross line 26 and has a large extension, or flap 11, on one of its edges and a smaller extension or flap 12, diagonally opposite to said lar e flap, on the opposite edge of said body, said flaps 11 and 12 extending from one end, or from near one end of said edge, to, or near to, its middle part. This blank is prepared for its intended purposes by dry gumming the flaps 11 and 12, and the surfaces 15 and 19; and by applying a wet adhesive to the surfaces 13 and 17. Then by folding over the body upon itself along the line 25 the adhesive surface 13 will adhere to surface 14, and the adhesive surface 17 will adhere to surface 18. The device then presents the appearance seen in Fig. 2, and a compartment 21 is formed to receive the senders message. 20 designates the unsealed return envelop which has the writing surface indi- Specification of Letters Patent.

cated by the guide lines 23. The two parts 20 and 21 are then folded together on the perforated line 26 and have the appearance seen in Fig. 3 which shows the rear side of the completed device ready for closure by turning down the dry-gummed flap 12, and by moistening the outer gummed portion of the flap 11 and turning it down across the flap 12 and sealing it upon the part 20.

When this device is used as a return letter sheet and envelop, the flap 11 should not be moistened so far in, as to cause it to adhere to flap 12. The receiver of this device opens flap 11 and finds the message sent to him, in apartment 21, and by tearing along the perforated line 26, separates the part 20 which will then open out flat as seen in Fig. 1. On this sheet 20 he makes. reply. Then by moistening the ummed surfaces 15 and 19 and sealing them down upon the opposite surfaces 16 and 29, re spectively, the part 20 becomes an envelop, in which may be put cards, note sheets, etc. and which is finally sealed for mailing by pasting down the flap 12.

It is apparent that when the device is made up as shown in Fig. 3, if all the interior adhesive surfaces are sealed to the corresponding opposite surfaces, there are provided two separable, individually closable compartments, for church collections.

When used for collection purposes the flap 11 should be moistened for sealing, down to line 27, so as to adhere to the surface 28 which is fully exposed after the apartment 20 has been closed; the outer portion of said flap 11, adhering to the body, or to the flap 12 of the body, 20, thus preserving the unity of the device until the compartments are purposely separated and passed on to the persons having charge of the different contributions.

hat I claim and desire to secure, is

A return envelop and letter sheet formed from a blank having an angular body, a nearly central cross perforated line, a single large gummed flap on one edge of said body, a single smaller gummed flap diagonally opposite to said large flap on the opposite edge 1 upon the part 20, when the blank has been 10 of said body, a gnnnned extension along one folded as described.
